Featuring former American Idol contestant Katharine McPhee leading an ensemble cast in the story of the making of a Broadway play, the fourth-place network is going all-out to promote the series, releasing a seven-minute extended sneak peek at the series.

In the clip, McPhee and co-stars Debra Messing, Megan Hilty, Jack Davenport and Anjelica Huston (among others) are joined by a "dream team" of writer-producers Neil Meron, Craig Zadan and Steven Spielberg as they discuss the concept for the series.

I've had this idea for quite a few years," Spielberg says. "I'm really interested in what happens backstage. In movies, I know exactly how to put together a story and how to put together a production but for me it's a complete mystery how they do it in theater."
